The cub and his mother, named Bahagia, are both healthy and will be in a den off-exhibit until May or early June, zoo officials said.

"The birth of any Sumatran tiger is a great contribution to this critically endangered species," Zoo Director Mary Healy said in a news release. "We are especially excited for this birth because it is the first time we have had a camera in the den, allowing zookeepers and veterinarians to keep a close eye on Bahagia and her cub."

Sumatran tigers are considered endangered, and are only found on the Indonesian island of Sumatra in the Malaysian Peninsula.

It is believed that there are fewer than 500 Sumatran tigers that exist in the wild and about 200 that live in zoos around the world.
